DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a skin material of a vehicle seat. More specifically, the pad material is covered with a skin material, and the pad material is extended in a width direction provided on a terminal side of the skin material. The present invention relates to a mounting structure for a skin material of a vehicle seat configured to lock a formed hook member to a locking portion formed on a seat frame side.

[0002]

2. Description of the Related Art Conventionally, FIGS. 6 (a), 6 (b), 6 (c)
As shown in FIGS. 7 (a) and 7 (b), a seat cushion 1 for a vehicle seat is formed by integrally forming a seat frame 2 made of a wire frame or the like and a pad material 3, and the surface of the pad material 3 is a skin material. 5 and is formed.

As shown in FIGS. 6B and 6C, a skin material 5 is provided.
A hook member 7 made of a synthetic resin is attached to the end 5a of the pad member 3, and a hook 7a in the shape of a hook on the end of the hook member 7 is inserted into the recess 3a formed on the back side of the pad material 3, and is located in the recess 3a. It is locked to a seat frame 2 made of a wire frame or the like or a locking portion 4 formed on the seat frame 2 side.

However, in such a conventional structure for mounting a skin material of a vehicle seat, a locking operation for locking with a hook member or the like is complicated, and a small change in the seat shape, for example, a pad material 3 is required. When the size, thickness, curvature of the hook member 7 and the like are slightly changed, the followability to these small changes is poor, and the hook member 7 is synthesized as shown in FIGS. 7 (a) and 7 (b). In the case of resin, the hook member 7
If the dimension L1 on the base end 7b side is long, it is difficult to bend, and if the base end 7b side is thick, it may be difficult to sew it to the end 5a of the skin material 5. Was.

Further, when the seat frame 2 and the pad material 3 are integrally formed, the pad material 3b is formed in a state in which the pad material 3b by integral foaming adheres to the seat frame 2 in the concave portion 3a formed on the back surface side of the pad material 3. It becomes difficult to lock the hook 7a of the hook member 7 to the seat frame 2 or the locking portion 4 formed on the seat frame 2 side, and this locking work becomes longer as the length L of the hook member 7 becomes longer. The length of breaking the pad material 3b becomes long, which is difficult.

SUMMARY OF THE INVENTION It is an object of the present invention to easily and quickly perform a locking operation using a hook member, improve the ability to follow small changes in the sheet shape, and perform a simple and quick sewing operation between the end portion of the skin material and the hook member. And the degree of freedom can be given to the change of the length of the base end side of the hook member, the work of assembling the sheet can be performed easily and quickly, and the appearance of the external shape can be improved. An object of the present invention is to provide a structure for mounting a skin material of a vehicle seat.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a vehicle seat seat mounting structure according to the first aspect of the present invention covers a pad material with a skin material. And a hook member formed on the terminal side of the skin material and formed to be long in the width direction to be locked by a locking portion formed on the seat frame side. A thin first flexible member having a hook member on the terminal side of the skin material fixed to the terminal side of the skin material;
A member and a substantially U-shaped cross section integrally formed on the terminal side of the first member
And a second member made of a synthetic resin having a character shape, wherein the second member is locked by a locking portion formed of a wire frame integrally formed with the pad material.

According to a second aspect of the present invention, the first member of the hook member is a net, a nonwoven fabric, a woven fabric, a cold cloth, a cotton cloth, a cotton tape, a synthetic resin sheet. Characterized by comprising any of the following.

According to a third aspect of the present invention, in the vehicle seat mounting structure, a plurality of slits are provided at appropriate intervals along a longitudinal direction of the second member on the second member of the hook member. Is formed.

According to a fourth aspect of the present invention, in the vehicle seat mounting structure, a projection is formed on an inner surface of the second member of the hook member to prevent the locking portion from falling off. It is characterized by being.

According to the first aspect of the present invention, the hook member provided on the terminal side of the skin material has the flexibility to be fixed to the terminal side of the skin material. A thin first member, and a second member made of synthetic resin having a substantially U-shaped cross section integrally formed on the terminal side of the first member, wherein the second member is formed from a wire frame integrally formed with a pad material. The hook member is adapted to be locked by the hook member, so that the presence of the thin first member having flexibility of the hook member can improve the followability of the hook member, and the engagement of the second member of the hook member can be improved. The second member of the hook member can be rotated in a small space because the insertion and locking of the hook member is easy, and the sewing work between the thin first member having flexibility and the end portion of the skin material becomes easy. The length of the flexible first member is changed by changing the length of the first member. Can be changed easily, it is possible to reduce the amount of expensive skin material, it is possible to reduce the amount of the second member having a rigidity.

According to a second aspect of the present invention, the first member of the hook member is formed of a net, a nonwoven fabric, a woven fabric, a cold cloth, a cotton cloth, a cotton tape, or a synthetic material. Since it is made of a resin sheet or the like, it has flexibility, can easily perform sewing, and can easily change the length of the cross section of the hook member in the length direction by adjusting the length of the first member by cutting or the like. .

Further, according to the third aspect of the present invention, in the vehicle seat covering structure, a plurality of hook members are provided on the second member at appropriate intervals along the longitudinal direction of the second member. Since the slit of the hook member is formed,
It can be easily bent along the longitudinal direction of the member.

Further, according to the structure for mounting a skin material of a vehicle seat according to a fourth aspect of the present invention, a projection is formed on the inner surface of the second member of the hook member to prevent the locking portion from falling off. Therefore, the second member can be easily and reliably locked to the locking portion formed on the seat frame side, and the rotation of the second member of the hook member can be performed in a small space,
The followability of the hook member can be improved, and the hook member can be prevented from coming off.
